Hi,
we are using nested PGs in non-trivial Nifi flows. The flow of one of
these inner PGs is itself version controlled in Nifi Registry. And this
inner PG is used in several instances at different places within the
outer PGs.
Depending on the use case, the instances of the inner PGs need different
configuration settings.
So far (up to Nifi 1.14) we just assigned different parameter contexts
to the different instances of the inner PG and it worked fine. All
instances of the inner PG link back to the same version controlled flow
in the registry. So it was relatively simple to maintain changes to the
flow configuration of the inner PG and keep everything consistent.
But now (Nifi 1.16.0) it seems that the name of the parameter context is
part of the data that is stored in the registry. At least we get
warnings that the inner PGs have been modified (see attached image). And
therefore it is now impossible to save the outer PGs to the registry -
as there are uncommitted changes to the inner PGs.
And of course it's also impossible to commit the inner PGs - at least we
could not keep them all linked to the same flow in the registry, as they
are now all assumed to be different.
I'm aware that there have been changes to the parameter contexts and
that they support inheritance now. Perhaps it's obvious, but I do not
yet understand if and how we can use this to support our use case.
Any hint would be a great help and very much appreciated.
Just observed: While "Version | Show local changes" lists the modified
parameter context as local change, the command "Version | Revert local
changes" does not revert this alleged change. You have to manually
re-assign the original parameter context (or remove the context,
depending on what is stored in the registry).
Thanks a lot
